Grease Trap In School Kitchen

School Kitchen Grease Management September Checklist UK

Date Published

After six weeks of reduced activity or complete shutdown, school kitchens across the UK are coming back to life for the start of a new academic year. Ovens are being switched back on, deliveries are arriving and catering teams are preparing to serve hundreds, in some cases thousands, of meals again. But there is one part of the kitchen that can easily be overlooked during the September restart: the grease management system.

Grease traps, kitchen drainage and fats, oils and grease (FOG) management systems that have seen little or no use during the summer break.  You shouldn't simply assume they will be ready for another busy term without a proper check. 

A problem that went unnoticed at the end of July can quickly become a blockage, unpleasant odour or operational headache once the kitchen returns to full capacity.

Before the first full weeks of service get underway, here is a practical school kitchen grease management checklist we would recommend you run through  ready for the new term.


1. Check Your Grease Trap Before Full Kitchen Service Resumes

The grease trap is one of the most important parts of a commercial kitchen's drainage system. Its job is to capture fats, oils and grease before they can travel further into the drainage network. If a grease trap wasn't fully cleaned before the summer shutdown, accumulated FOG and food waste may have remained inside it throughout the break.

Before returning to normal service, check that the grease trap is operating correctly and isn't already approaching the point where it needs cleaning.

Starting a new term with a grease trap that is already partially full means it could reach capacity much sooner than expected.

2. Look Out for Signs Your Grease Trap Needs Cleaning

Grease trap problems aren't always immediately obvious, but there are several warning signs catering teams should be aware of.

Unpleasant smells around the kitchen or grease trap, slow-draining sinks, visible grease accumulation and unusual drainage noises can all indicate that something isn't working as it should.

If there is any doubt about the condition of the system following the summer break then the best course of action is to arrange a professional grease trap inspection. This will allow it to be professionally cleaned and can help identify potential problems before the kitchen gets seriously busy.

3. Don't Forget the Kitchen Drainage

The grease trap is only one part of the overall system. Kitchen drainage also needs to cope with a sudden return to high-volume use after several weeks of relatively little activity. Existing deposits of grease, food waste and other debris within pipework can contribute to slow drainage and eventually lead to blockages.

A blocked kitchen drain during the first few weeks of term isn't just inconvenient. In a busy school catering environment, it can potentially affect meal preparation and disrupt the operation of the kitchen.

Professional kitchen drain cleaning can remove accumulated deposits and help ensure the system is ready for the demands of the new academic year.

4. Review How Your Kitchen Handles Fats, Oils and Grease

September is also a good opportunity to refresh kitchen procedures with catering staff.

Fats, oils and grease should never simply be washed down sinks. Although they may enter the drain as liquids, particularly when mixed with hot water, they can cool and solidify further along the drainage system.

Over time, these deposits can restrict the pipe and contribute to serious blockages.

Good kitchen practices, effective grease separation and responsible FOG waste management all help reduce the amount of grease entering the drainage system in the first place.

5. Check Your Grease Trap Maintenance Schedule

When was the grease trap last professionally serviced? If the answer isn't immediately available, September is a good time to review the school's maintenance arrangements.

How frequently a grease trap needs cleaning depends on the size of the system, the number of meals being prepared and the volume of FOG generated by the kitchen. A large secondary school preparing hundreds of meals every day may have very different requirements from a smaller primary school kitchen.

Rather than relying on reactive call-outs when something goes wrong, planned grease trap maintenance allows servicing to be scheduled around the needs of the kitchen and the school calendar.

For education sites, this can also make it easier to arrange more substantial maintenance work during quieter periods or school holidays.

6. Make Sure FOG Waste Is Being Removed Correctly

Removing grease from the trap is only part of the job. The collected waste also needs to be handled and disposed of appropriately. Professional FOG waste removal provides schools with a managed solution for the grease and waste collected from commercial kitchen systems.

Keeping clear maintenance and waste records can also help schools, academies and facilities management teams demonstrate that grease management is being handled responsibly across their sites.

7. Use September to Get Ready for Unblocktober

The timing of the new school year also provides an opportunity to look ahead to Unblocktober. This is the annual campaign encouraging homes and businesses to think more carefully about what they put down their drains. Fats, oils and grease are a major part of that conversation.

For schools, colleges and universities, the campaign can be a useful reminder for catering teams about good kitchen practices and responsible FOG disposal.

It could even become an educational opportunity beyond the kitchen, helping pupils understand why cooking oil, grease, wet wipes and other unsuitable materials shouldn't be put into the drainage system.

Planned Grease Management for Schools, Colleges and Universities

Commercial kitchens within the education sector face some unusual demands. During term time they can operate at extremely high volumes, preparing hundreds or thousands of meals each week. Then, during school holidays, activity can fall dramatically or stop altogether. That makes having the right grease management programme particularly important.

I contacted Grease Guru looking for advice, they promptly offered a free no commitment site survey to determine our requirements. The surveyor was very helpful and explained all our options. We were then given a detailed proposal which we confirmed was acceptable with the water authority before continuing. The traps were installed soon after and have been running great since.

Frequently Asked Questions

How often should a school grease trap be cleaned?

There isn't a single maintenance interval suitable for every school. Cleaning frequency depends on factors including grease trap capacity, the number of meals prepared and the amount of fats, oils and grease produced. A planned maintenance programme can establish an appropriate schedule for your kitchen.

Should a grease trap be checked after the summer holidays?

Yes. If the kitchen has been closed or operating at reduced capacity for several weeks, checking the grease trap before returning to full service is sensible, particularly if it wasn't professionally cleaned immediately before the summer shutdown.

Can grease traps be serviced during school holidays?

Yes. School holidays can provide an ideal opportunity to schedule grease trap cleaning and other planned kitchen drainage maintenance while catering operations are reduced or the kitchen is closed.

Yes. Grease Guru provides commercial grease management services for schools, colleges, universities and other education facilities across the UK.
